[Asterisk-Users] SIP register= bug?

[John Todd]

I am seeing some very peculiar things in the routines that REGISTER 
my * server with several accounts.

I saw this on my console:
.

.
NOTICE[5126]: File chan_sip.c, Line 1878 (sip_reg_timeout): 
Registration timed out, trying again
NOTICE[5126]: File chan_sip.c, Line 1878 (sip_reg_timeout): 
Registration timed out, trying again
NOTICE[5126]: File chan_sip.c, Line 1878 (sip_reg_timeout): 
Registration timed out, trying again
NOTICE[5126]: File chan_sip.c, Line 1878 (sip_reg_timeout): 
Registration timed out, trying again

and so, being curious, I did this to see what was happening during 
one of these "trying again" transactions:

garthim# tethereal port sip
Capturing on fxp0
   0.000000 asterisk.foo.com -> 10.0.1.100 SIP Request: REGISTER

What's wrong here?  you ask.

Well, asterisk appears to be trying to "REGISTER" with one of my 
ATA-186's, which is clearly not a Good Thing.  Somehow, * has swapped 
some IP address information somewhere in it's little head. 
10.0.1.100 is my ATA-186, and thus should not be getting REGISTER 
attempts _from_ asterisk, and is thus throwing errors.  Note that 
195.37.77.101 resolves to fox.iptel.org


Here's my sip.conf, distilled and anonymized:
